Rewinding Machine safety operation guide -
Fifth, the tool change operation:
1. The bottom knife replacement is handled by the mechanic.
2. The rewinding machine must be stopped when the upper round knife is replaced.
3. After removing the round blade, replace the new blade and fix it.
4. Install the round knife seat, adjust the angle, and lower the round knife to make it close to the bottom knife.
5, running, paper test knife, paper edge is not, smooth.
6. The tightness and depth of the blade and the bottom knife should be controlled properly, not too tight, otherwise the new knife
The film will roll the knife; it should not be too loose, otherwise it will jump the knife and the hair; not too deep, otherwise it will cause double trimming; too shallow will jump the knife.

Belt rewinding machine design and working principle ---
6 nipple guardrail
The nip guard is a sturdy mesh protector located between the belt roller and the unloader. The nipple guardrail acts as a protective device during the rewinding process. It prevents contact with rotating sticks.
The vertically moving fence is controlled by hydraulics. In the upper position, the safety lock prevents the fence from falling. When the guardrail falls, the cylinder compression safety lock opens.
The nipple is in the upper position when the reel is stopped. When rewinding, it must fall or the winder cannot be turned on.
7 paper feed roller
The reel is moved from the roll to the unloading station by a hydraulically controlled ejector mounted on the frame.
The minimum roll diameter that the pusher roll can be pushed open but cannot be pushed open with the smallest roll is 400 mm (15.7 in)
